In Celestial Mechanics the equation:

LP = w + N (Longitude of the Perihelion = Argument of the Perihelion + Longitude of the Ascending Node)

is confusing.

Both "LP" and "N" are on the Ecliptic Plane but "w" is not.

"w" is on the Elliptic Plane with a tilt of "i" Inclination from the Ecliptic Plane at "N".

Even though "i" is small then projection of "w" onto the x-y axis of the Ecliptic Plane is different than just plain "w".

How do you explain for this discrepancy?
